Many times conservators make “unique” mixtures of these adhesives which may contain something that the solvent extractions cannot remove.

Thus, there is no perfect method for the pretreatment.

Older samples have a lower concentration of radiocarbon, but they can be (and often are) counted for longer periods of time to compensate for this lower concentration.

By counting longer, the counting uncertainty in a radiocarbon measurement on a very old sample can be the same as that on a young sample.

The laboratory has over 30 years of experience in the application of radiocarbon dating and associated research and is happy to help with all aspects of the radiocarbon dating process from project design to calibration and statistical analysis.

This enables the best use to be made of the radiocarbon technique.

The radiocarbon age must then be calibrated to determine the sample's age in calendar years.

Measurements can be made with a high degree of precision. Aardsma submitted a sample from a reed mat known to be over 5,000 years old.

The measurement, before calibration, came back with an error bar of /- about 60 radiocarbon years. It should be noted that these measurement uncertainties do not increase linearly as one goes back in time.

Thus it is possible in some instances for two samples from a few decades apart to have the same radiocarbon concentration today, and hence the same apparent radiocarbon age.

This happens whenever there is a wiggle in the curve at the time the samples died.
